Technical Field

[0001] This application relates to the field of door opener technology, and more particularly to a door opener structure for a horizontally opposed drive brown frame opening device. Background Technology

[0002] The shedding device of the hem frame in a ribbon weaving machine is the core component that controls the opening and closing of the warp yarns and forms the weave opening. The shedding knife, as the key actuator of this device, drives the hem frame to achieve the shedding action through reciprocating motion. However, traditional shedding knives are usually designed as an integrated structure, tightly connected to the frame by bolts or pins, and the distance between adjacent shedding knives is small. When replacing a single bearing, it is necessary to first remove the associated transmission chain, limit device and protective cover, and then unscrew the fixing bolts one by one. This results in the need to disassemble multiple shedding knives in sequence during maintenance or replacement, making the disassembly process cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a shut-off structure for a horizontally opposed drive brown frame opening device in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a shut-off knife structure for a horizontally opposed drive brown frame opening device, including a shut-off knife arm, the shut-off knife arm having a protruding extension, a slot penetrating the protruding extension, and a related blade being movably mounted on the slot. The switch arm includes a main body and a clamping block. Both the main body and the clamping block have arc-shaped slots on opposite sides. When the main body and the clamping block abut against each other, the two sets of arc-shaped slots form a first mounting groove and a first bearing component is movably mounted thereon. The main body is also provided with a second mounting groove and a second bearing component is movably mounted thereon.

[0019] Reference Figures 1-4A shut-off structure for a horizontally opposed drive brown frame opening device includes a shut-off arm 1, the shut-off arm 1 having a protruding extension 11, the protruding extension 11 having a slot 111 penetrating the protruding extension 11, a shut-off blade 2 being movably mounted on the slot 111, the shut-off blade 2 being movably mounted in the slot 111, the extension distance of which can be adjusted along the length direction of the slot 111, so that it can be adapted to horizontally opposed drive brown frames of different widths and different opening strokes without replacing the entire shut-off arm 1; the slot 111 can limit the shut-off blade 2. The switch arm 1 includes a main body 12 and a clamping block 13. The main body 12 and the protruding extension 11 are integrally formed. Both the main body 12 and the clamping block 13 have arc-shaped grooves 14 on opposite sides. When the main body 12 and the clamping block 13 abut against each other, the two sets of arc-shaped grooves 14 form a first mounting groove 121 and movably mount a first bearing component 3. The two sets of arc-shaped grooves 14 are semi-circular in structure, thereby providing radial support for the first bearing component 3. The main body 12 also has a second mounting groove and movably mounts a second bearing component 4. The second mounting slot also adopts a circular structure. The first bearing component 3 and the second bearing component 4 are used to connect different shaft components. The double bearings form two-point support. Compared with the single-point support of a single bearing, it can effectively suppress the radial runout when the knife arm 1 is running, avoid the deviation of the brown frame opening accuracy caused by the runout, and improve the overall operating stability of the device. In addition, the first bearing component 3 plays the core role of power transmission and bears the main radial force during the operation of the knife arm. It is under high-frequency force and rolling friction for a long time, which makes it prone to wear and failure. When the clamping block 13 separates from or abuts against the main body 12, the clamping block 13 supports or moves away from the first bearing component 3. In traditional designs, the bearing needs to be removed from the device along with the entire knife-handling arm 1 before it can be replaced. However, in this design, the clamping block 13 separates from the main body 12, and the first bearing component 3 can be taken out directly without disassembling the knife-handling arm 1 body, which greatly reduces the difficulty of maintenance.

[0020] Based on the above structure, the switch blade 2 is installed on the protruding extension 11 of the switch arm 1, thereby connecting the switch blade 2 and the switch arm 1. Then, the first bearing 3 is installed in the arc-shaped groove 14 of the main body 12, and the clamping block 13 is placed against the main body 12, so that the first bearing 3 is located between the main body 12 and the clamping block 13. Then, the second bearing 4 is installed on the first mounting groove 121 of the main body 12. Then, several switches are arranged in sequence so that the shaft passes through several second bearings 4. Finally, another shaft passes through the first bearing. The first bearing component 3 is opened during long-term operation. During this process, the first bearing component 3 plays the role of power transmission and radial force bearing, which makes it prone to wear. When maintenance is required, it is only necessary to remove the support shaft and separate the clamping block 13 from the main body 12. The outer ring of the first bearing component 3 loses the support of the clamping block 13 and can be directly removed from the arc-shaped groove 14 of the main body 12. This facilitates the replacement or maintenance by the operator, thereby enabling rapid maintenance of the first bearing component 3 and solving the problems of high operation difficulty and cumbersome operation when the tool is closed.

[0021] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The clamping block 13 is provided with two sets of spaced mounting holes 131. The two sets of mounting holes 131 are located on both sides of the arc-shaped groove 14. The arrangement of the two sets of mounting holes 131 can increase the number of locking positions. The bottom of the main body 12 is provided with a first threaded groove corresponding to the mounting hole 131. When the clamping block 13 abuts against the main body 12, the first threaded groove and the mounting hole 131 are aligned and threaded together with the first bolt 15, so that the clamping block 13 is fixedly connected to the bottom of the main body 12. The two sets of mounting holes 131 are symmetrically distributed on both sides of the arc-shaped groove 14. When the bolt is tightened, the clamping block 13 can be evenly pressured to avoid the first bearing 3 from being deviated by force. In addition, the detachability of the threaded connection ensures the connection strength between the clamping block 13 and the main body 12, and facilitates the later disassembly and maintenance of the bearing, taking into account both firmness and convenience.

[0022] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4The extended portion 11 is provided with through holes 112 that penetrate the slot 111. Several through holes 112 are provided and are spaced apart along the length of the extended portion 11. The blade 2 is provided with several through holes 21 spaced apart. When the blade 2 is installed in the slot 111, the several through holes 21 are aligned with the several through holes 112 and a pin 22 is installed to fix the blade 2 on the extended portion 11. The spaced distribution of the multiple through holes 112 allows the blade 2 to move along the length of the extended portion 11 according to the width requirement of the brown frame opening, thereby adjusting the installation position and adapting to brown frames of different specifications, improving the versatility of the device. At the same time, the cooperation between the pin 22 and the through holes 112 enables quick positioning operations, thereby improving the speed of installation and disassembly.

[0023] In one embodiment, reference is made to Figures 1-3 The blade 2 is also provided with a second threaded groove 23, and the protruding extension 11 is provided with an opening 113 at the position corresponding to the second threaded groove 23. When the blade 2 is fixed on the protruding extension 11, a second bolt 24 is threadedly connected between the second threaded groove 23 and the opening 113. The threaded connection of the second bolt 24 can make up for the deficiencies of the pin positioning. The bolt connection has stronger anti-loosening ability, which can prevent the blade 2 from shifting due to vibration during long-term high-frequency drive, improve the structural reliability, and the threaded connection can be adapted to different stress conditions by adjusting the bolt preload, thus enhancing the load adaptability of the device. The second threaded groove 23 is provided in several places and is distributed at intervals along the length and width of the blade 2. The number of openings 113 and the second threaded groove 23 are corresponding. The multi-directional distribution of threaded grooves allows users to select bolt installation points according to actual stress requirements, flexibly adjust the connection strength, adapt to brown frames with different loads, and multiple connection points can disperse the local stress of the blade 2, avoid overload damage to a single threaded groove, and further improve the durability of the structure.

[0024] In one embodiment, reference is made to Figure 1 and Figure 2 The switch blade 2 has a receiving part 25, and both the receiving part 25 and the protruding part 11 are rectangular in structure. When the switch blade 2 is connected to the switch arm 1, the receiving part 25 is located on the protruding part 11. During installation, the outer edge of the receiving part 25 fits against the slot 111 of the protruding part 11. The through hole 21 and the second threaded groove 23 are both located on the receiving part 25. The rectangular surface fit design makes the positioning of the switch blade 2 and the protruding part 11 more accurate, avoids left and right offset during installation, ensures the straightness of the opening action of the frame, concentrates all connection points on the receiving part 25, and the force can be evenly transmitted to the protruding part 11 through the rectangular surface, reducing local stress concentration and extending the service life of the switch blade 2.

[0025] In one embodiment, reference is made to Figure 1 and Figure 2 The main body 12 is provided with an arc-shaped end 122. Two sets of arc-shaped end 122 are provided and symmetrically distributed on the main body 12. The arc design can reduce airflow resistance during device operation in high-speed driving scenarios, reduce energy consumption, and at the same time avoid sharp edges from scratching surrounding components, improving safety. Furthermore, the symmetrical arc structure optimizes the mechanical distribution of the main body 12, which can better disperse the horizontal impact force, improve the overall deformation resistance of the switch arm 1, and also make it easier for the operator to hold.
